LG Dryer TE1 Error Code: Meaning, Causes & Fix

Thermistor error — a problem was detected with the dryer's thermistor (temperature sensor). LG renders it tE1 and lists it with tE3; owner manuals group tE1 through tE7 as temperature sensor failure.

tE1 reports that the control detected a problem with the dryer's thermistor — the temperature sensor it relies on to regulate heat. LG's published consumer guidance goes no further than that: it does not name which physical sensor tE1 belongs to, and it publishes no resistance value for owners to test against, so any page quoting you an exact ohm figure for tE1 is not quoting LG. LG's own remedy is a factory reset (the PF procedure); if tE1 returns after it, LG directs you to request service, where the sensor, its wiring and the control are separated by a technician's tests. The most useful thing to know about tE1 is how little LG claims about it — because that restraint is itself the verified picture. LG's consumer documentation says a problem was detected with the dryer's thermistor, offers a factory reset, and then stops, directing you to service; its manuals widen the lens only slightly, grouping tE1 through tE7 as temperature sensor failure. Nowhere does LG's owner-facing material assign tE1 to one named sensor position, publish a resistance an owner can meter against, or offer a cleaning cure. Pages that supply those specifics are drawing on technician folklore or other models' service data. Treating tE1 as a circuit-level report — sensor, its connection, or the control reading it — and following LG's reset-then-service ladder keeps you aligned with what the manufacturer actually documents, and it is why this page's fix section is short: the honest owner remedy genuinely is one reset deep.

What causes the TE1 code on a LG dryer?

Thermistor failure

The temperature sensor itself has failed — the cause LG names for the whole tE family.

A transient control glitch

LG's first remedy for tE1 is its factory reset, which exists because some tE1 events are one-off sensing glitches rather than dead parts.

Sensor wiring or control fault (service diagnosis)

If a reset does not clear tE1 and the sensor is later proven sound, the fault sits in the connection between sensor and control, or in the control itself — LG leaves that separation to service.

A one-off sensing glitch after a power disturbance

LG's published remedy for tE1 is revealing about its causes: before any repair, LG prescribes the same factory reset it uses for the PF power-failure code — unplug the dryer, hold Start/Pause for five seconds while it is unpowered, restore power and run a cycle. A manufacturer only leads with a reset when a meaningful share of cases are transient control or sensing upsets rather than dead hardware. A tE1 that appears once, close in time to an outage, a breaker trip or a storm, and never returns after that reset belongs to this branch and needs no part.

A connector disturbed by recent work on the dryer

tE1 that begins immediately after the dryer was repaired, moved, or opened for an unrelated job — a belt change, a blower clean-out, a new element — should be read as a wiring story before a sensor story. The thermistor's connector lives in the same working areas those jobs disturb, and a plug left half-seated or a lead pinched during reassembly produces exactly the out-of-range reading the control reports as tE1. LG's guidance ends at 'request service' for persistent tE1, but the service visit that cures this version often does nothing more glamorous than reseating the connection the last job loosened.

The control misreading a healthy sensor

When tE1 survives a thermistor replacement, the remaining suspect is the control itself: the sensor can be reporting correctly while the board interprets its signal as out of range. This is the pattern behind the 'replaced the thermistor, still tE1' searches — LG lists no owner test that separates sensor from control, and its manuals group the whole tE1 to tE7 range as 'temperature sensor failure: turn off the dryer and call for service', which is LG deliberately reserving that separation for a technician with the model's service documentation.

Checks to run before you replace anything

1. Do LG's factory reset first, exactly as published: unplug the dryer (or trip its breaker), hold Start/Pause for 5 seconds while it is unpowered, restore power and run a cycle. A tE1 that never returns was the glitch case.
2. Note when tE1 appears: immediately at start-up on every cycle points to a hard sensor-circuit fault; tE1 only after a recent repair or panel work points first at a connector disturbed during that work.
3. Keep the lint filter and its housing clean while you work through this — it costs nothing, and a choked filter housing distorts the temperatures every sensor in the exhaust path sees.
4. Apply LG's reset once and log the result precisely: unplug or trip the breaker, hold Start/Pause for a full five seconds with the power off, restore power, and run a normal heated cycle. A code that clears and stays away through several loads was the glitch case; a code that returns on the first or second cycle has passed LG's own test and graduated to service — repeating the reset weekly does not change that verdict.
5. Separate tE1 from its cold-weather sibling before assuming hardware: LG explains that tE2 also reports a thermistor problem but normally arises in cold conditions, when extra humidity from steam cycles cools the duct too fast. A code that only appears on Steam Fresh or steam options in winter, and never on ordinary heated cycles, follows the tE2 branch (LG's remedy there is running Steam Fresh with the load size set to Big), while tE1 on plain cycles stays on the service path.
6. Record the exact moment tE1 strikes across two or three attempts: a code present the instant a cycle starts, before any heat is produced, indicates the control is failing its start-up check of the sensor circuit, whereas a code arriving part-way through heating suggests a reading that drifts out of range as temperatures change — write the pattern down, because it is the first thing a service technician will ask and it cannot be reconstructed later.
7. Check the simple surroundings LG's troubleshooting always starts from: confirm the dryer is properly plugged into its rated outlet and that no breaker has half-tripped, since a control running on a disturbed supply can produce sensor-family codes among its complaints. Restore a clean, verified supply before the reset test so the test itself is meaningful.

How to fix lg dryer error code te1?

1. Run the factory reset once (above). LG's instruction if tE1 persists after it is unambiguous: the unit requires a repair service — request it rather than repeatedly resetting.
2. If the dryer was recently serviced or moved, have the thermistor connector and harness checked and reseated before any part is ordered; a disturbed connector is the cheapest tE1 there is.
3. Thermistor replacement, where a technician's test condemns the sensor, is the repair — judged against the model's own service information, not a generic resistance figure.
4. Follow LG's sequence without improvising a longer one: factory reset first (unplug, hold Start/Pause five seconds unpowered, restore, run a cycle), and if tE1 or tE3 persists after that reset, LG states the unit may require a repair service — request it. LG publishes no cleaning, adjustment or owner part-swap for tE1, and treating the reset as the whole remedy when the code returns is how a sensor fault gets run for months.
5. If a technician condemns the thermistor, have the connector and harness proven in the same visit rather than accepting a sensor-only swap on faith: a new sensor plugged into a corroded or loose connector reproduces tE1 within days, and the second visit costs more than the extra minutes of checking would have.
6. When tE1 follows a thermistor replacement you have already had done, go back to the same repairer with the history rather than ordering another sensor: LG's documentation gives no second owner remedy, and a repeat code after a replacement is precisely the evidence that the fault sits in the wiring or the control — the two branches only a service diagnosis can separate.
7. Keep the lint filter washed and its housing vacuumed while the dryer awaits service: it will not cure a tE1, but a filmed filter distorts exhaust temperatures across every sensor in the path, and removing that distortion gives the technician clean readings to judge the actual sensor against.

The part that usually fails: Thermistor (temperature sensor)

LG names the thermistor as the faulty component for tE1 but publishes no owner-testable resistance value for it; sensor-versus-control separation is a service test against your model's service documentation.

Lg dryer error code te1 reset

LG's factory reset: unplug or trip the breaker, hold Start/Pause 5 seconds while unpowered, restore power and run a cycle. tE1 that returns after this reset is, by LG's own guidance, a service case.

LG dryer codes clear with a power cycle: unplug for about 5 minutes, hold the Power button for a few seconds while unplugged on some models, restore power and run a test load. Flow Sense bars and codes like D80 are computed fresh from airflow measurements each cycle, so they only 'reset' by fixing the airflow — a power cycle alone cannot clear a genuine restriction.

Why does the TE1 code keep coming back?

TE1 returning with a good sensor reading at the board connector = board input fault (rare). tE1's return pattern is its biography. A code that never returns after LG's reset was an event, not a failure, and needs no follow-up beyond noting the date. A code that returns immediately, at start-up, on every attempt describes a hard break in what the control can see — the sensor circuit is simply not reporting. A code that returns only sometimes, often part-way through hot cycles or after the dryer has been running back-to-back loads, describes a marginal connection or a reading that leaves its range as things heat and expand, and it will usually harden into the always-on version over time. In every returning case LG's instruction is the same — service — but arriving with the pattern written down (when it strikes, on which cycles, after what recent work) converts a vague 'thermistor error' visit into a targeted diagnosis.

How to stop TE1 coming back

• Thermistor failure: The temperature sensor itself has failed — the cause LG names for the whole tE family.
• A transient control glitch: LG's first remedy for tE1 is its factory reset, which exists because some tE1 events are one-off sensing glitches rather than dead parts.
• Sensor wiring or control fault (service diagnosis): If a reset does not clear tE1 and the sensor is later proven sound, the fault sits in the connection between sensor and control, or in the control itself — LG leaves that separation to service.

Retrieving stored fault codes on LG dryers

LG dryers have an installation/test mode (used at install to verify venting and, on gas models, the gas connection) and a service test mode that steps through motor, heater, steam and sensor checks while showing stored codes (the tE family and others). The entry sequence is model-specific and printed in the service manual; running the install test after any vent work is the fastest way to confirm a Flow Sense fix.

Codes TE1 gets confused with

NP — No current detected at the heater — displayed nP. LG's manuals define it for electric dryers: the electric dryer power cord is not connected correctly, or the house power supply is incorrect. nP is an electric-dryer code, not a gas-dryer code.

D90 — Flow Sense: exhaust about 90% blocked — serious vent restriction (mid-level of the D80/D90/D95 family). D90 means LG's Flow Sense measures the exhaust at roughly 90% restricted.

D95 — Flow Sense: exhaust about 95% blocked — the dryer stops for safety (top of the D80/D90/D95 family). D95 is the Flow Sense end-state: the exhaust is effectively blocked (~95%), so the LG dryer cuts heat/cycle to protect itself and your house.

H5 — Humidity sensor error — the dryer's moisture (humidity) sensor is faulty or its signal is implausible. H5 is one of the least-documented LG dryer codes (it belongs to the moisture-sensing system on sensor-dry models).
